PAPER BOX.

SPECIFICATIONforming part of Letters Patent No. 567,897, dated September 15, 1896. Application filed May 13, 1896. Serial No. 591,360. (No model.)V

To @ZZ whom it map/concern: Be it known that I, ALEXANDRE F. GIRARD, of `Wacdin the county of McLennan and State of Texas, have invented a new and useful Improvement in Paper Boxes, of which the following is a specification. A

My invention relates to that class of boxes known as knockdown, sold in a flattenedout position to avoid taking up space when not for immediate use and put together at It consists in a box of this character which may be easily and securely locked and also in an improved blank to accomplish this purpose. Y

It further consists in the details of construction and arrangement of parts hereinafter more fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a viewof my improved blank, and Fig. 2 is a perspective view of my improved box with three sides locked and the-remaining side knocked down. t s ,s

Referring to the drawings, A designatesthe bottom of the box, and a, a', a?, and d3 the lines stamped or scored in the blank, on which the side and end portions B and B are folded. Each side and end portion has its outside edge cut in a straight line. Hence the blank can be easily cut from `a square sheet of cardboard or other suitable materiaLas there are no curved lines forming its edges.

In each end portion B, Imakecutsextending diagonally from the intersection of the lines d a', ct d2, a2 d3, and d3 Ct to points b near the corners b of the blank, whence I forty-five degrees with said former cut to the points b2, and` then curve it gradually outward to the edge of the, blank. e The angular cuts and the curved cut form, respectively,the inner edge c of the said end portions Band the engaging edges c and c2 of my locking devices D.

The side portions B are each formed by cuts extending from the intersection of the scored lines hereinbefo're mentioned to the outer edge of the blank, forming the curved edge c3, as shown in Fig. l. The said por tions B are furthermore provided with curved slits d to receive the lock I).

To forni the box, the side portions B are turned up on the scored lines d and d2. The end portions B are also turned up and the points `of the locks D passed from the outside of the said side portions B through the curved slit d into the box, thus securely locking the parts. i e y The curved or cut-away edges cB-allow the locks D to fit closely against the side portions B', avoiding unseemly bulges of the corners and also permitting of nice adjustment between the top and bottom of the box.

A box cutin accordance with my invention can beeasily and expeditiously folded and locked, and the blank, by reason ofits straightedge, can be easily made.

It will be especially observed that it is customary for boxes of this character to have sharp cornersextending beyond the outside folding the sides and ends thereof, or evenin handling the blanks preparatory to using the same. My invention obviates this difculty,

as none of the edges extend beyond the lthe scored lines on which the side and end portions are folded to a point near the outside edge of said end portions, the direction thereof being then turned at an angle of forty-five degrees to said former cut and curved outwardly,said side portions being provided with an in Wardly-curved edge extending also from the intersection of said lines to the outer edge thereof whereby bulging of the ends in the folded box is avoided and a curved slit adapt ed to receive the lock formed in the end portions, as and for the purpose set forth.

2. In a box of the character herein described, the blank of which said box is c ut, said blank being made in one piece having straight outer edges scored lines on which the 'end and side portions are formed, and provided at each corner with a cut extending diagonally from the intersection of said scored lines to a point near the outside edge of said blank, thence at an angle of forty-live degrees to said former edge of theblank and liable to be torn off in i IOO direction and thence extending outwardly to the edge of said blank, the direction thereof being reversed at that point and curved in- Wardly to the starting-point thereof, forming locks D for the end portions and a curved edge c3 for the side portions of the boX, said side portions being provided With curved slits to receive said locks, as and for the purpose set forth.
